Unfortunately, that is not sufficient. With the three patchs you listed
and the configure options above, the resulting GHC still fails to build
the 'magic' due to something going wrong with hsc2hs:

  Configuring magic-1.1...
  Building magic-1.1...
  Preprocessing library magic-1.1...
  /usr/bin/ld: dist/build/Magic/Data_hsc_make.o: relocation R_X86_64_32 against 
    `.rodata' can not be used when making a shared object; recompile with -fPIC
  /usr/bin/ld: final link failed: Nonrepresentable section on output
